RHEL7 notes

Below are some helpful tips when working with RHEL7. They are not always recommended however sometimes helpful, especially when new to RHEL7…..

Disable dynamic network interface naming:

# vim /etc/default/grub

add the following to GRUB_CMDLINE_LINUX line
“biosdevname=0 net.ifnames=0”

# grub2-mkconfig –output=/boot/grub2/grub.cfg

reboot

Set Hostname:

# hostnamectl set-hostname “hostname”

Disable network manager and firewalld:

# systemctl stop NetworkManager

# systemctl disable NetworkManager

# systemctl stop firewalld

# systemctl disable firewalld

Register with subscription-manager:

# subscription-manager list –available

# subscription-manager attach –pool=

# subscription-manager repos –list

       # subscription-manager repos –disable=*

# subscription-manager repos –enable <repo-name>

      # subscription-manager repos –enable=rhel-7-server-rpms –enable=rhel-7-server-extras-rpms
